Answer: Scientific laws are created when a theory has stood the test of time and cannot be proven wrong. A scientific law is a statement based on repeated experimental observations that describes some aspects of the universe.
Answer:
A scientific law describes repeated observations under a given set of conditions. These laws are not too specific, and they imply a casual relationship. These laws do not explain why something occurs, they merely state that something will occur if the given conditions are met. Therefore, the formation of a scientific law is a result of repeated observations. An example is Newton's first law of motion, which gives certain conditions for an object, such as no force acting on it, and then describes what the object will do in that situation, that is, remain in motion or remain stationary.

What would happen if cells could not reproduce?
Answer:
Everything living would die
Answer:
Without DNA, cells could not reproduce, which would mean extinction of the species. Normally, the nucleus makes copies of chromosomal DNA, then segments of DNA recombine, and next the chromosomes divide twice, forming four haploid egg or sperm cells.

Explanation:
The cell membrane (plasma membrane) is describe as a highly selective barrier composed of a lipid bi-layer. This structure plays an important role in moving molecules across the cell membrane in order for the cell to maintain homeostasis. If the cell is unable to take in the materials it needs or remove what it does not need, the cell may die. This inability of cells to maintain homeostasis may cause sickness or even death of an organism. Why is it important that the cell membrane is highly selective?
Answer:
Selective permeability is a property of cellular membranes that only allows certain molecules to enter or exit the cell. This is important for the cell to maintain its internal order irrespective of the changes to the environment. ... Movement across a selectively permeable membrane can occur actively or passively
Explanation:
The cell membrane is highly selective in order to prevent certain ions/molecules from entering or exiting the cell. This feature is fundamental for maintaining the homeostasis of the cell.
The homeostasis of the cell refers to the internal balance that cells must have to carry out their metabolic functions (e.g., reproduction, growth, differentiation, etc).The cell membrane is a highly selective lipid bilayer due substances do not cross it indiscriminately but instead it allows the entry/exit of specific particles into the cell.There are some substances that can move across the cell membrane in favor of a concentration gradient (passive transport) and others that move against a concentration gradient (active transport).In conclusion, the cell membrane is highly selective in order to prevent certain ions/molecules from entering or exiting the cell.

Runoff that contains fertilizers can cause increased levels of nitrogen in the ocean. What is a possible result of these increased nitrogen levels that may have harmful effects that can disrupt the diversity of ocean ecosystems?
Answer:
Explanation:
Increased nitrogen level in ocean water can lead to excessive growth of aquatic plants in the ocean which in turn leads to high oxygen (dissolved oxygen) uptake by these plants when they decompose. The overgrowth of these plants also prevent light penetration in the ocean water. All these can affect other aquatic organisms particularly those that depend on these dissolved oxygen and/or light penetration (such as fish and crustaceans).
A caterpillar has an exoskeleton and feeds on many leaves before it makes a cocoon and becomes a butterfly. Which type of organism is a caterpillar? an autotroph and an invertebrate a heterotroph and an invertebrate an autotroph and a vertebrate a heterotroph and a vertebrate
Answer:
heterotroph and an invertebrate
Explanation:
Animals have been classified into being AUTOTROPHIC OR HETEROTROPHIC based on their nutrition while they are also classified as VERTEBRATE OR INVERTEBRATES based on their skeleton. A heterotrophic animal is one which depends on other organisms to obtain energy or food while an invertebrate is an animal that lacks a vertebrae column or backbone.
In this case, caterpillars are said to feed on many leaves before it makes a cocoon and becomes a butterfly. This means it relies on plants (leaves) for food, hence, it is HETEROTROPHIC. Also, it has an exoskeleton i.e. skeleton present outside the body. This means that it does not possess any bone inside to form the backbone, and hence it is an INVERTEBRATE.

In certain fish, blue scales (B) and red scales (R) are codominant. Cross a blue
fish and red fish. What is the genotype of the offspring? What is the phenotype
of the offspring? **
Answer:
the genotype of the offspring would be RB, BR, RB, BR (well the genetic pattern of the fish varies for example the fish could have Bg meaning dominant blue and maybe recessive green im making this up and going into detail too much). the phenotype would have to be some sort of mix.
Explanation:
the genotype is the genes on the inside. i just use a table to mix it and assumed both fish were just pure blue/pure red. the phenotype is what's visible. it would be a mix such as maybe purple or red here and blue there. this is since they are both dominant and have to be expressed. same for blood types (AB blood). sorry for late answer.

Explanation:
Different RNA have different functions such as the mRNA is the linear form that codes for the polypeptide chain, rRNA is the ribosomal RNA and tRNA is the transfer RNA that carries the amino acid.
What are the functions of the different types of RNA?The RNAs, such as mRNA, tRNA, and rRNA, are synthesized in the nucleus and later come into the cytoplasm in the case of the eukaryotic cell, while the prokaryotes perform all the functions in the cytoplasm. The mRNA is formed by the process of transcription from the gene that carries the genetic information for the polypeptide chain synthesis. The tRNA transports the amino acids and reads the mRNA codons, which have a cloverleaf structure. The ribosomal RNA is made up of rRNA and proteins and takes part in translation.
Hence, mRNA is the linear form that codes for the polypeptide chain, rRNA is the ribosomal RNA, and tRNA is the transfer RNA that transports amino acids.

B) It controls which substances enter and exit the cell
C) It prevents substances from entering the cell
D) It prevents substances from exiting the cell
Answer:
it controls which substances enter and exit the cel
Explanation:
I think this is the answer but I could be wrong bc I am only in Earth Environmental Science but pretty sure is the correct answer. Let me know if I was correct though
It controls which substances enter and exit the cell which describes the function of the cell membrane. So, the correct option is (B).
What is Cell Membrane?The cell membrane is also known as the plasma membrane. It is defined as the biological membrane which separates and protects the interior of all cells from the external environment.
Cells are surrounded by this cell membrane, the components of the cell, large, water-soluble, highly charged molecules such as proteins, nucleic acids, carbohydrates and substances that are involved in cellular metabolism.
Outside the cell, the surrounding water-based environment contains ions, acids and bases that are toxic to the cell, as well as nutrients that the cell must absorb in order to survive and grow.
Thus, it controls which substances enter and exit the cell which describes the function of the cell membrane. So, the correct option is (B).

Explanation:
A student was observing (looking at) a section (part) of cells under a microscope. She noticed (saw) they had a box-like shape, bean-shaped organelles and were green. She also noticed (saw) a nucleus that was to the side of the cell. What was she examining? An Animal Cell A virus A bacterium A plant cell
Answer:
A plant cell.
Explanation:
Plant cells are part of multicellular organisms. They form tissues and are differentiated. If we see a section of plant cells, we can see that they have a box-like shape. This happens because plant cells, besides the membrane, are surrounded by a cell wall, which is rigid and gives the cell this form.
They also do photosynthesis, which is a metabolic process where they obtain energy from the radiation of the sun. To capture the photons they have pigments, especially a green pigment called chlorophyll. The chlorophyll is not free in the cytoplasm, it is contained in a bean-shaped organelle called chloroplast, and therefore they give the chloroplast this distinctive green color.
